neoplasms;

2. Organ
3. Tissue
4. Cell
5. Organelle
Key Points
I. Cell Overview
A. Hierarchy of organization
1. Atoms -- tiny building blocks of all matter
2. Molecules -- carbohydrates, proteins, lipids, nucleic acids
3. Organelles -- miniature systems carrying out functions within the
cell
4. Cells -- fundamental unit of living organisms
Copyright © Texas Education Agency, 2012. All rights reserved.
II. Cell Structures
A. Cell Membrane -- a semi-permeable membrane acting to protect the
internal cell structures and assist in cell transport
1. Passive Transport -- requiring no extra energy to transport particles
in or out of a cell as in the passively rafting using the current of the
river to assist
a. Diffusion -- passive movement of a particle from a higher
concentration to an area of lower concentration like
perfume
b. Facilitated diffusion -- a substance that carries a molecule
across; akin to passing a pail of rocks to a person who
dumps it empty and returns for more
c. Osmosis -- the movement of water across a semipermeable membrane from an area of high low solute
concentration to an area higher in solute concentration to
balance out the water on both sides
d. Filtration -- different from osmosis in that pressure is
applied to move water and its dissolved materials across a
membrane, such as when you squeeze a water gun or the
blood pressure forcing water and solutes through kidneys
2. Active Transport -- a method of cell transport requiring extra energy
in the form of ATP and a protein to carry molecules across an area
already fully concentrated such as rafting against the current of the
river
a. Endocytosis -- the physical movement of a particle into a
cell resulting with an enclosed vesicle formed from the
enveloping of the cell membrane
b. Phagocytosis -- cell eating such as white blood cells
ingesting bacteria to prevent infections
c. Pinocytosis -- cell drinking
d. Exocytosis -- the physical movement of particles out of the
cell such as secretion of insulin from pancreatic cells
3. Diseases related to cell transport
a. Cystic Fibrosis -- a defect in the membrane channel carrier
proteins affecting the simple diffusion of sodium and
chloride causing thick mucus production and clogging
organs
b. Diabetes mellitus (DM) -- a disorder of facilitated diffusion
where insulin, the carrier molecule for glucose, is not
enough or is ineffective to transport into cells; this results in
hyperglycemia thus affecting the osmotic pressure of all
cells resulting in dehydrating the cells of fluid as glucose
concentration increases extracellularly and water is drawn
from within the cell. This explains why diabetics frequently
urinate with traces or high amounts of glucose in the urine.

c. Familial Hypercholesterolemia -- A genetic disorder of
endocytosis where a fatty-protein called Low-Density
Lipoprotein (LDL-the “bad” cholesterol) is not transported
across the cell membrane together with cholesterol to make
other lipids for cell use but rather hangs out in the blood to
accumulate and clog the blood vessels
B. Cytoplasm -- the internal formative material needed for cell survival;
likened to the egg-white needed for an embryo chick to survive
C. Nucleus -- the brain of the cell that dictates the activities of the
organelles within the cell; like “City Hall” controlling the activities of
city departments
1. Chromatin -- found in the nucleus, this material contains the DNA
material or “blueprints” needed to make new cells
2. Nucleolus -- an orbital structure located within the nucleus which
synthesizes RNA and ribosomes, the organelles responsible for
getting the materials needed to work on cellular infrastructure using
our genetic blueprints
D. Ribosomes -- an organelle composed of one-part RNA and one-part
enzyme found singly in cytoplasm or on endoplasmic reticulum is the
site of cell repair and reproduction; this is compared to a
manufacturing company of the building materials used for cell
remodel and repair
E. Centrosomes -- the general area containing centrioles, the organelles
needed to prepare for the construction of new cells, like building
contractors making new buildings; centrioles prepare cell for mitosis
F. Mitochondria -- a cellular power plant, this organelle generates the
body’s energy needs by supplying ATP for body processes through
the process of cellular respiration:
C6H12O6 + 6O2
Glucose + Oxygen
6CO2 + 6H2O + ATP
Carbon Dioxide + Water + Energy
G. Endoplasmic Reticulum -- found with or without ribosomes on its
surface, this organelle becomes the road system within a cell
1. Rough ER -- contains ribosomes; is the site of protein synthesis
2. Smooth ER -- has no ribosomes; synthesizes fats and steroids
H. Golgi Apparatus -- this organelle, looking like a stack of flattened
sacs, is the packing and shipping center of the cell; works by
receiving all proteins produced by the ER and aids in transporting out
of the cell
Copyright © Texas Education Agency, 2012. All rights reserved.
I. Lysosomes -- organelles likened to an internal waste-management
system maintaining cellular health by ingesting and destroying
invading organisms
J. Accessory structures
1. Flagella -- structure used to propel entire cell
2. Cilia -- hair-like structure used to propel objects from the surface of
certain specialized cells such as in the bronchi or in the fallopian
tubes
3. Diseases of Accessory structures
a. Tay-Sachs: Caused by lysosomal defect where there is an
enzyme deficiency rendering the lysosome unable to digest
and toxins accumulate especially in the lysosomes of
neurons resulting in mental retardation and death
b. Cigarettes and paralyzed cilia -- a side-effect of smoking;
lungs are left unable to clear particles
III. Cellular Reproduction
A. Cell Cycle- the total life of a eukaryotic or normal cell comprised of
two main stages:
1. Interphase- period or no cellular duplication
2. Mitosis -- period of cellular division through asexual reproduction
resulting with 46 chromosomes or 23 pairs of chromosomes
containing all the genetic blue print needed to duplicate an identical
daughter cell through four stages:
a. Prophase (pro- before) -- nucleus disappears and spindle
begins to gather all chromosomal material
b. Metaphase (meta- between) -- chromosomes move to
center
c. Anaphase (ana- apart) -- chromosomes begin to move
apart
d. Telophase (telo- end or across) – chromosomes move to
far end, spindle disappears, and nuclear membrane
reappears
B. Meiosis -- the process of reproduction of gametes or sex cells
containing one half of the chromosomes from each respective parent
C. Diseases of Cellular Reproduction
1. Cancer or Neoplasms -- wild, uncontrolled mitotic formations
leading to too many cells being formed into weird benign or
malignant masses
2. Benign tumors -- the proliferation of slow-growing cells kept within
a confined space and not affecting surrounding tissues; they are
not usually life-threatening
3. Malignant tumors -- are cancerous tumors (cancer or crab-like)
invading surrounding tissues or spreading through the lymphatic

Objective:
Students will build a 3-D model of an animal cell using recycled or “trash” materials only. The
items in your model should look like the structure it depicts and be as anatomically correct as
possible. For example, the Golgi Apparatus has folded membranes, so it should look folded.
Each structure must be neatly labeled. Your project can be no larger than 2x2x2. NO Food
items or other material that will mold, rot, or smell may be used.
